Y 8"`Clai1ns. This invention relates generally to-turnstiles, gates`and'like passage-controlling.,barriers and has for its object to causesuch barriers ,to operate silently.To this end provision is made forbring- `5 ingthe barriers .l to a comparatively easy stop,

which, in addition to doing away with noise objectionable to passingpatrons and others nearby, avoids injurious shock to the barrier-.Amechanism.A

As it isv necessary to give'a turnstile a sturdy, rugged structure, V,toenable it to withstand the rough treatment to which itisvordinarilyfsubjected in use, .the problem of practicallyeasing theturnstile toa-noiseless stop, presents many serious diiflculties. 1

Stops and brakes of Various kinds have been applied tov turnstiles inaneffort.V to solve the problem but have been unsatisfactory, owing tofailure Ato meet the requirements `insisted vupon by transportationcompanies and othen large users of turnstiles. e

Asidefrom the main requirementV of silent operation, the brake must not`only be capableof bringing the barrier to a quick, easy.-stop, re-

' gardless of itsmomentum, but Vmust furthermore check anytendency ofthe barrier' to vvibrate or oscillate on reaching its homel position,Vasany such action would be ,highly objectionable in causing confusionand Ydelay in operation and to risks'of serious injury.

The brake must also be of comparatively simpleworking co=ndition,.without requiringreadjustf ment,`repair or replacement, as anyinterruption of or withdrawal from service causes serious embarrassmentto'the operating company --and its patrons; particularlyn busy.locations 'where hundreds ofpeople crowd through the turnstilecontrolled-passages during rush hours.Y f -'Io meet the above and otherrequirements, employ a brake of the hydraulic type which `is silent inVoperation and entirely capable of rapidly reducing fthe 4momentum of theturnstile `barrier andbringing '-it r to la stop4 without Vshock l orjar.

Toinsure a smooth, VeasyV applicationV and re. lease of the brake, Ipreferably employ a-simple cam action, the operationk of'whch isgraduah.comparativelyspeaking, and free ofk noise-pro;- duringshocks orjars. Y

'By `forming the cam on or in brake-.actuating lever, a single memberis;thus` made toserve with a turnstile barrier of `any numbervoffarm's,it being necessary 'only to provide each barrier arm with a stud orroller to coli operate with the cam-faced brake-actuating lever.

In the accompanying drawings, I have shown one Vform of Vmechanismsuitablevfor carrying my invention into effect but do not wish to beunder# stood asintending to limit myself to the same as various changesmay be made therein Ywithout departing from the spirit and scope of theinvention, as outlined in the appended claims;

Referring now to the drawings, I representsa standard; which serves asthe supporting pedestal of the turnstile.

Rotatably mounted in suitable bearingsof the 35i standard, there is anarmed barrier 2. The usual four armed type is shown, but it will beunder# stood` that a barrier having a greater or less num# ber" ofarmsmay be employed, yif desired. 'The arms3, of Vthe'barrier projectradially from and 40? barring entrance through the passage the turn-rv Ystile is intended to control.. -Y'lhej positioning lever cooperatesinthe usual manner v with la. pair of Y f rol1ers6,"6, carried by a disk`1,` securedto and rotating with the barrier head, above referredsto;there beingfour of such rollers equi-spaced about,` theturning `axisofthe head. Thepositioning lever 5 is pivoted at 8, and is yieldingly heldunder. pressure against thev rollers byv means fof' heavy springQm-fVThe turn-stile'shown is of .the well known ,type Vlili? NT OFFICE-iig?part with the 10f which requires the insertion of a coin to release itfor operation. The coin released lock consists of four lugs orprojections Ill, I0, etc., which are formed in part with the disk 1, andcooperating with the lugs there is a barrier locking pawl II, pivoted atI2, and yieldingly held in engaging relation with the lugs by a springI3.

A coin-actuated release lever. for the'locking pawl is shown at I 4.This lever has limited movement about a pivot, i5, and, under thekaction 'of a spring I6, the free end of the lever co-acts with a pin orstud I'I on the locking pawl to disengagev the latter and free theturnstile barrier for opera;-

tion. v

The usual provision is made,- by normally spacing the engaging end of'the locking'pawl'and the disk locking lug, next in line for engagement,somewhat apart, to permit the necessary .free :limited movement of theturnstile barrier to operate a coin finder carried by the positioninglever 5, the details Vof which Willnotrbe. given', as the de-z vte iswell known in the artand formano par-t d beipresent invention." i Inoperation of the mechanism thus y:farfalleseribnd, the free movement-.ofthe bar-rieris siii'- oimt to give the necessary` .motioni to .theposi-1 iionnglever. 5, to :swingitqabout itspivot and ad'mxce a coinfinder pin or slide carried thereby, through the coin chute.

The release of'l'thecoinis subsequentlybrought about in a well known manner:and Vtherefore need not bedescribed.

It will be understood that theabove described i turnstile isconveniently employed here for -purposes of Villustration only, to aidin showingthe application of my improved brake, jto -behereinafter morefully described, and may therefore be replaced by any other type or,form preferred, as

1 the brake is designed 4to o oact with .the turnstle barrier only andhas no cooperative relation with any other `part or element of themechanism.

, Before describing the brake at greaterzlength, I want rst to makeclear that the solution of the 2 problem of easingl theturnstile barrierto a noiseless .stop is not found in a brake .device 0;( the type -nowin common use as a door check and an automobile shock absorber. l Y, J Y

As such devices are constructed and applied to adoor or automobile,the-actuating lever thereof is permanently linked to the door frameorautomobile axle frame and, thus restricted, cooperates with one memberonly, vWhereas forfa turnstile, the actuating lever of the brakeniustbefree to enable it to coact successively with each of the several arms ofthebarrier. Y v Y Y The brake-actuating lever being thus left -free for:successive cooperationwith the barrier arms orf the turnstile, it isnecessary to provide 'suitable means for `bringing aboutpropertirnedengagement and'properly regulated. and controlled movementafter engagement, Vboth forY the .application af the brake anditsrelease and return .to norma-l I position, preparatory to the nextoperation. These a essental requirements` anefiective and satisfactoryturnstile brake and distinguish it from the door check and automobileshock absorber, in which such needs are not present.

Another distinguishing feature is the necessity in a turnstile brake foreliminating vibration or oscillation of the barrier as it reaches itshome position. No provision for this Ypurpose is made in either a doorcheck or an automobile shock absorber. The action of the spring latch ofthe ordinary dolock prevents vibration of the door land makes theprovision unnecessary and in the automobile shock absorber, suchvibration is not seriously objectionable and is considered negligible. Y

Recognizing, as the foregoing makes apparent, vtl'iat the ordinary doorcheck or shock absorber would not meet essental requirements of a,turnstile brake unless modied, I employ aconstruction, in which thebrake cylinder 3U, is mounted on the turnstile standard or an extensionthereof, in swch position that the brake-actuating lever '33 attachedAto .the p'iston,'projectsinto the path of travel'ofY a stud, roller orthe like 34, attached to the underside of each of the barrier arms 3.The brake-actuating lever 33 is yieldingly held 'thus advanced by aspring 35, which also serves to return the lever to normal positionafter each application of the brake. i Y

In Fig. l, the cam 36, of the brake-actuating lever., is formed beyondthe high point, indicated at BSI, .to present an inclined surface 35h,to the engaging roller 34 of the barrier and so cause thebrake-.actuating lever to be gradually returned by its spring to itsnormal position, preparatory to the next operation of the turnstile.

If quicker resetting action of the brake isdesired, it `may, be,obtained by shaping the cam face of the brake-actuating lever as shownin the Fig. 3 modification, in which the cam terminates Vat thehighpoint 36, the inclined surface 36h, of the Fig. l form being omitted topermit4 instant return of the Vlever as the barrier roller passes rthehighpoint of the-cam. f f- .Theftiming voi .the action ofithe brake iseffected byrextending the lever 33 morev or less into the path. oftravel of the barrier armLrollers for engagement therewith at anypredetermined point desired; 'The regulation of the brake, in itsapplication, is controlled Vvby va cam 36, formed in part, with thelever 33, for cooperation with the barrier arm rollers 3,4.

The fomnof the cam is such that the brake-is appplie'rl gradually, itspower increasing asthe barrier nears its home position, the effect ofwhich is toreduce the momentum of the barrierA and bring itvto anxeasy,noiseless stop.

y As the barrier Yreaches its home position, com, pleting an operation,the .barrier arm roller engaging the cam, cornes to rest vjust short -ofthe high point of the lcam, as shown in Fig.v Land is maintained thusuntil the beginning of the next operation.' ,Y

The -brake-actuating lever not 'being .fully thrown by .the cam,sufficient brake power remains available .to .check any tendency of thebarrier to oscillate `and as a result,A it may beput into immediateoperation again, no time interval being required .between thecompletionof one .operationand the beginning of the next. v

At the beginning of the next operation, the nrst movement of thebarriercarries ,the roller. engaging the cam over the high point thereof andenV to the descending portion and through the action vot, ,the spring,vinretractin'g the brake-actuating arm, it is returned to its normalposition for again 'being actuated to apply the brake, as the barrierreaches a predetermined I pointrin its travel.
